In the beginning of May, 1894, I found the species quite abundant 

 at Digne in lucerne fields on the Barcelonette road. I have not taken 

 it farther north than Coblentz. I am told that it is rare in Belgium, 

 but it does not appear to be so scarce there as in England, as every 

 Belgian entomologist will tell you that he has taken the butterfly at 

 some time or other. 



Mr. Raine informs me that at Hyeres daplidice is on the wing at 

 the end of February, occurs throughout the summer months, and is 

 found in the autumn, suggesting that there is a succession of broods 

 in the south. He has frequently reared the first and second broods, 

 the larvae feeding on wild mignonette. 



Pieris chloridice is a very pretty species belonging to the fauna of 

 South-eastern Europe, not occurring farther westward than Turkey. 

 It appears to be more common in Asia Minor. My series was taken 

 in Armenia. 



I now return to the genus Euchloi, E. belemia is purely a southern 

 species, occurring in the south of Spain along the North African 

 coast, certainly as far eastward as Palestine, as I have received speci- 

 mens from that locality. How far north it extends into Spain and 

 Portugal cannot be ascertained from any published records, but we 

 are certain of the fact that it does not occur north of the Pyrenees. 

 The variety glance is the second brood ; it is somewhat larger, the 

 black apical markings are duller, but the distinctive difference is on 

 the under side of the hind wings, on which the green assumes a 

 yellowish tint, and the white " tiger-like " stripes become enlarged 

 and are devoid of silver. 



Euchlo'e belia is another southern species, although extending much 

 farther north than the preceding. It is one of the commonest 

 butterflies on the Riviera, and occurs in Palestine and along the north 

 coast of Africa. It is reported, according to Dr. Frey, to have been 

 once taken at Sion, in Switzerland, is met with at Lyons, is recorded 

 as occurring near Paris, and I have seen a specimen sold at Stevens' 

 as having been taken in England. I think it quite possible that a 

 strong flier like belia could certainly migrate to the centre, if not to 

 the north of Europe, and possibly to the south of England. This 

 species is interesting in having two distinct forms — var. a?/sonia, the 

 second brood, and var. simplonia, the mountain variety. The black 

 apical markings are lighter in ausonia, and the ground-colour of the 

 under side of the hind wings is more yellow than in the type. As in 

 belemia, specimens of the second brood are larger than those of the first. 

 It is an early species, the first brood emerging in the south of France at 

 the end of February. In T894, curiously enough, I found both broods 

 out together. Belia was getting over, and var. ausonia was just 

 coming out. Mr. Raine tells me that belia only occurs in March, 

 April, and May ; the second brood, ausonia, appears at the end of 

 May, and the butterfly is not seen again until the following spring. He 

 further states that he bred specimens which had been four years in 

 the pupal state. I can only recollect one other species of butterfly,
